Minnesota is a very moisture rich state, we get snow and rain frequently enough that they tend to clean themselves. We do not recommend getting on your roof to clean the panels.
Should you remove snow? Generally, snow doesn’t need to be removed – it will typically slide off on its own. Most panel installations are tilted at an angle, and snow will naturally slide off as it melts. If snow persists on your panels, you can also invest in tools like a solar panel snow rake, which makes it easy to safely remove snow covering on solar panels. It is important NOT to use a standard broom, shovel, or other non-specialized tool to remove snow from panels, as they can scratch the panel glass and lower your power production.
